Then If I run pnpm build with my production config fetch(\"https://nexasoft.netlify.app/api/allnames/\"), my app build correctly in my computer, then I push it to github where the Netlify deploy fails with this:[ERROR] Could not resolve \"/opt/build/repo/adaptors/express/vite.config.ts\"I also run the command, netlify dev, witch opens the content from my site but still I get the 404 message trying to access my data from Mongo.So I decided to install, Netlyfy functions to serverless. I created a new function get_contacts witch made my MongoDB conection and call (there I import my .env variables like, process.env…).

"text": "I’m starting a new app services + realm project and have a couple questions. When I purchase a dedicated cluster and go into production, do the Functions / Endpoints I create in my app services incur additional billing/compute charges? If not, does that mean then that all of the compute overhead of running Functions/Endpoints for my middleware run on the same server as my Mongo instance?Since I’m new maybe these questions are covered somewhere but also, when I deploy Mongo on Atlas dedicated instance, does that mean there are 3 instances of Mongo running (the default redundant configuration of Mongo) and therefore Mongo actually runs on 3 separate EC2 instances? And, if so, do the functions I create run on one of those instances?If app services Functions run on say Lambda then I would expect to see a pricing page for Functions. But, I don’t see one.So, this is really a question about cost and also about scaling. Depending on where my Functions run / get deployed, how would I make plans on how to scale them? What if my Functions get extremely high use but my data tier / the actual Mongo activity isn’t very high relatively speaking. If I need to scale out my Functions but keep my Mongo server running on modest server, how would I do this?If the Functions actually run on the Mongo servers themselves (which I guess they do bc I don’t see additional pricing info for Functions), I would need to purchase more Mongo instances even if all I really need is more compute capacity for my Functions layer?Thanks, basically I’m considering Functions for nearly all of my middleware needs. I’m an experienced developer and am comfortable creating Lambda functions + API Gateway, etc. But, after learning as much as I can about Realm (which is absolutely perfect for my application) and the App Services product + node Functions, it seems as though I could just deploy nearly all of my middleware logic into App Services + Functions.Any input greatly appreciated, thanks",

When you reset sync, it doesn’t clear the data in the backing collections it just resets the sync history and builds up a synthetic history from the existing state on the server.

Looking further down through the logs, you can see that this object id actually originated from a previous write from your app a day earlier.

For some reason, the update picks up the older timestamped item even though it receives the new timestamp item. My hypothesis is that, two updates happen at the same time, checks that the document does not contain the item inside the array and each of them overwrite on one another. This only happens for a very small number of times. My questions is, is there a way to make it thread safe such that if two updates happen at the same time, both of them happen serially, rather than in parallel? Is the query param and the aggregation pipeline param thread safe, do they happen in one lock step? If not, what can I do to mitigate this?For ex: I have UpdateOne({id: ‘1234’, … additional condition to check if the item exists inside the array or not}, [{…aggregation pipeline to set the item inside the array which uses concatArray}]}Let me know if you need additional clarifications.",

Based on the error, it seems that you are trying to access the oplog from the local database of MongoDB Atlas.Shared tiers (M0/M2/M5) have certain restrictions in place that make them slightly different from a dedicated clusters. Please refer to the Manage Clusters and Atlas M0 (Free Cluster), M2, and M5 Limitations documentation for more details. Although we strive to make them functionally equivalent, some features are exclusively available on dedicated clusters. In this particular case, one restriction is that when performing a regex query on an oplog in a shared tier deployment, it must be preceded by an anchor (^).Could you modify your query so that it includes this anchor and see if it works?

If the 13 indexes still exist in each collection, then you end up with 91 indexes and files. Updating an index is O(log n) so if you still update 13 indexes per collection you are roughly looking at the same amount of work.Your splitting has some potential performance improvement if and only if you can eliminate some indexes for some of the collections. For example, abc_v4 might not need all the 13 original indexes, so an update on abc_v4 will touch less indexes. This is assuming that some indexes are not needed for abc_v4.If you think that updating indexes is the culprit, then optimizing the indexes might be a better avenue. Since all your queries including field_3 with a specific value (v1 to v7), field_3 is probably (should be) present in all indexes. One way to reduce the number of indexes to update is to have more indexes but partial indexes. This is with, again, assuming that some indexes are not needed for some collections. The partialFilterExpression will be on field_3. Basically, you would partition the indexes without partitioning the data.I am surprised thatmongodump is giving me better resultcompared to $out/$merge as there is extra disk I/O involve with mongodump/restore and potentially network I/O if mongodump/restore is performed from another machine. I think $merge will be a very bad choice for your use-case since it compares existing documents, while $out does not perform this check. I really cannot understand how dump/restore could be faster than $out. So if your performance numbers are based on $merge rather than $out, then you should revise them. What ever path you choose create your indexes after the partitioning.As I wrote disk I/O above, I thought that partitioning per database rather than per collection could be much better as you could leverage the directoryPerDB option where you make each database directory be a symlink to 7 different disks.",

With mongodump/restore, you will have 3 processes so 3 times the amount of context switch. With $out the data stays on the server, with dump/restore data is exchanged from mongod to mongodump, then from mongodump to mongorestore and finally from mongorestore to mongod.

Today, the Realm-Web SDK provides a bunch of convenience APIs for accessing data stored on MongoDB Atlas and proxied through the MongoDB Realm platform which provides authentication and authorization as well as static hosting and severless functions which abstract away a bunch of the middleware logic that a web developer would normally need to write and deliver. But the actual fetching of data must still be performed by the developer with a traditional request/response model. Wouldn’t it be cool if you could leverage the same Realm Sync primitives that the mobile Realm SDKs leverage? We are even kicking around ideas of persisting the data in the browser which would enable developers to write fully offline PWAs with Realm Javascript!If you could help us answer some questions then we can look to add this to the product roadmap.

How is it going?I’m having the same issue I don’t have a solution for this apart of changing the database type or applying try and catches everywhere the database client fires a query - sad -. However, I wanted to share my thoughts in case somebody else faces the same issue.In my case, our team is running a NodeJs container + Prisma.io ORM to handle the database work over a GCP Cloud Run instance too.This issue arises very consistently when multiple queries hit the db serverless instance - around 3 read consecutive/parallel operations would trigger it fairly easily and consistently -, causing the same Broken pipe error you have found.My hypothesis is that the issue lies on how serverless instances are handling connections and its consequent scaling/provisioning whenever a query tries to hit the db. Looking at the charts mongodb atlas provides, I found that that error matches a connection drop on the database side (see the snapshot attached).\nimage3130×754 154 KB\nThis connection, of course, would have been closed by the db itself. Open thoughts:1.- GCP Cloud Run runs containers, which means that connections pools would be set and used/reused as long as the container is active and running while using MongoClient. Not knowing what specifically triggers a mongodb serverless instantiation, leaves me thinking if those reused connections could be causing this if, for example, mongodb serverless expect 1 query = 1 connection.2.- In my case, 3 queries are being fired, where the third one more often is the one that gets this Broken Pipe error. I wonder if queries 1 and 2 gets its own connection while the latter gets, let’s say, connection 1 reused and that could cause mongodb serverless to close the connection (e.g. 1 connection = 1 response and then closes).3.- I haven’t found documentation on any of this nor options to configure the scaling behaviour of mongodb serverless instances. I’ve read that min connections could be set at the client side on this doc https://www.mongodb.com/docs/manual/reference/connection-string/#mongodb-urioption-urioption.minPoolSize4.- Nevertheless, that’s an option for the client side and I don’t know if that could impact somehow the behaviour of mongodb serverless scaling (one way i think it could affect tho, is if the connections on the pool gets to 0 on the client for X ms while opening a new one and that somehow indicates mongodb serverless instance to scale down, dropping the connections and causing the consequent error)It’d be nice to have someone form mongodb to give some light on these issues. I know that serverless instances are now in preview, so we’re aware stuff like this can happen.In the meantime, to stays in the safe side, we’ve moved prod to a shared cluster, and it’s working like a charm.Hope this helps get the discussion moving ",

Would that be correct ? does also RUST driver differ in this behavior in some way or another that could be affecting the retry behavior ?Thanks a lot!",
